MULTIPLE-COLOR DOT-PRINTING MACHINE. v

Application iled May 31, 1924. Serial No. 717,048.

To all 'whom it may concer/n:

Be it known that I, LIEVEN Lotus DE SMET, a subject of the King of Belgiumv (having taken out his first United States citizenship papers), and a resident' of borough of Fair' Lawn, in the county o-f Bergen and State of New( Jersey, have invented a new and Improved Multiple-Color Dot-Printing Machine, of which the followling is a full, clear, and exact description.

plurality of rollers is provided associated together in such a manner that the same color or wdifferent colors may be'i deposited therefrom on a strip of cloth passing through the machine. y

A still further object more specifically is to provide in a printing machine a plurality of printing drums adapted to print different colors, the arrangement being such that recesses are provided in certain of the drums for preventing smearing of the paint deposited on the cloth. A still further object of the invention is to provide a printing machine for printing dots on fabric, wherein. dotsl of different colors may be provided, having means designed to retain the fabric and other parts in alignment to produce a proper registry throughout.

By the construction of printing machines, particularly those known as flocking ma'-l chines, a colored liquid is deposited in dots on the fabric and arranged in certain designsp This liquid is known aspaint and f produces ralsed dots simulating, to a certain extent, embroidery. Hereto-fore,. machines of this character applied only a single colored paint arranged to produce differentl designs. Where more than one color was desired to implrove'the design, it was necessary lo pass t e cloth through a second machine and this was very diiicult as it usually was impossible to produce a proper registry of the different dots. n

In the present invention means have `been provided forprinting or 'depositing three 'different colored paints in a stripof fabric 'as 1t passes once through the machine. It

is, of course, evident thata greater number of colors or less number could be used without de arting' from the spirit of the invention, t e only requirement being vto increase or iecrease the number of printing rollers use Referring to the accompanying drawings by numerals, l indicates a frame of anvldesired kind which is provided with vertically adjustable bearings 2gv adapted-to support the shafts of the various drums 3, 4k, and 5. These drums ma be of any desired kind and are prefere ly`^ hollow, as shown in Figure 3, for the sake of lightness. The outer surface of these drumsV are smooth in order to provide a pro er surface for supporting the cloth as 1t passes ihereover. Each of the adjustable bearings or boxes 2 is guided in its respective guiding members 6 carried by the frame 1 and associated with each of the drums 3, 4 and A threaded member 7 is rigidly secured byva screws 7 and the respective worm wheels are continually maintained in mesh with the respective worms 10, 11 and 12 rigidly secured to a shaft 13. A worm wheel 14 is also connected with the shaft 13 and meshes with a worm 15 mounted on the shaft 16, vwhich shaft carries a hand wheel 1T whereby the parts may be manually adjusted and the various bearing boxes 2 raised and lowered simultaneously. As illustrated in Figures 2 and 3, the arrangement j ust described is positioned on both sides of the machine, so that'there is only one hand wheel 1T. This arrangement permits the various drums, 3, 4 and 5 to be bodil; 'adjusted toward and from the printing drums 1S, 19 and 20. Thedrums, 3, 4, and 5 are positively driven, while the printing drums 18,

19 and 20 are driven by friction. ln order toV positively drive the lower drums, .each

drum has a. large gear wheel 21 secured thereto and these gear wheels are connected by the respective idlers 22 and 23,v while a pinion 24 meshes-with one of the gears 21. This pinion is rigidly secured to shaft 25,

' which shaft carries a pulley 26. A belt 27 passes over theV pulley 26 and over a small pulley 28 driven by the `motor 29. Arranged near the bottom of frame 1 and at each end are rollers 30 and 31, roller 30 bein free to rotate whenthe cloth 32 is pulled.

Ro ler 31 isrdriven by a belt 33 passing over a pulley 34 connectedwith thc roller 31 and over a pulley 35 connected-to thesshaft- 25.

i The cloth 32 is a-heavy cloth of some, kind known ,as a foundation cloth, said cloth cpassingrupwardly over drum 3 and from whereby a proper foundation or movable -a roper registry may1 Y or er to assist 'this a thence 1n a'horizontal line over drums 4 and 5, and then down to the roller 31 on which .it is wound. The pullof rolle-r 31 maintains this foundation cloth tight,

horizontal base is provided for 4the fabric 36, which is to be rinted. This fabric is wound on-a roller 3 and'is pulled through the machine lby the friction of the various parts including the drums 3 and 4 and the' printing rollers 18 td 20. Y

VEach of the printing drums is provided with a. large gear 38 -meshingwith the various idlers 39, 40, 41 and 42, which ,idlers Vact to hold the rollers in .alignment and also to cause them to rotate 1n unison, whereby be maintained. 1n 4 Y gnment and proper/ registry, each ofthe printing drums is prov1 ed with a guiding disk 43 'and coacting with the {espective disks guiding wheels or ulleys 44, 45, 46 and 47. These guiding pul eys are connected to theijrespective idler gears 39 to 42 b the respective shafts 48, 49, 50and 51. l'hese shafts are rotatably mounted in suitable bearings 52 connected to the frame 1. By this method the printing drums are permitted a free rotation produced by friction and also permitted to yield upwardly or away from the drums 3, 4r and 5. AThough this yielding motion is permitted, the drums will all remain in alignment and in registry by reason of the gears and guiding disks just described.

'The various printing drums 18, 19 and 20 are of` identical construction except for the position of the apertures of the outside surface illustrated particularly in Figs. 4, 5 and 6. AFigure 7 illustrates in section part of the printing drum 19 and associated parts. From this figure it will be observed that the drum 19 is formed with a4 plurality of apertures 53, which may be arranged in any desired order, als, for instance, as shown in Figure 3, whereby straight rows of dots will be produced. Arranged between the apertures 53 are depressions 54 for accommodating 'the dots 55 caused by the paint flowing through the. apertures 56 of .the drum 18 (Figs. 4 and 5). As the cloth passes beneath the drum 18, a single series of dots will be provided, as indicated in Figure 4, and when the cloth reaches the drum 19, the depressions or notches 54 will accommodate the dots 55 provided by drum 18 and in turn will provide additional dots or printed matter 57, which may be of the same color or of different color. When the cloth reachesthe third drum; namely, drum 20, a third dot 58 will be provided which may be of the same color or of a different color than those before provided. In addition the printing drum 2O is provided with a pair of recesses or depressions 59 and 60 to accommodate the dots provided by printing drums 18 and 19. It will, of course, be understood that the various apertures inthe various drums may be arranged to produce .any desired con guration and that the notches and depressions, 54, 59 and 60 must falls therethrough on to the bracket 61 and on to the feeding knife 65, which is of comparatively thin metal and which is re'ferably also resilient. .The feeding kni e 65 y is preferably provided with forwardly extending flanges 66 on each side to hold the 694 having an adjustable weight 69,i

whereby the blade 68 may be brought under any desired tension. The bar 69 extendsbe'- yond the drum and is mounted in any suitable manner on the frame. In this way Esub-i stantially all of the paint released front. the trough 62 willv bel maintained.- betweenf` the 'blades 65 and 68, or until the paint has been deposited on the fab-ric 36 through the apertures 53. By this construction and arrangement of parts, the fabric 36 may be printed as rapidly as the paint canllow through any 2,0 of the apertures 63.

In order to adjust the various printing drums, special means have been provided to producean accurate adjustment to cause a proper alignment. Each of the drums is provided with a flange 7 0, on which the respective gear rings or gears 38, 39 and 40 are .looselymounted `A plurality of wedges 71 is carried by each of the flanges 70, and after the gear rings or gears `have been properly adjusted, these'wedges are forced in until they tightly clamp the parts together. yIn

orderl to adjust ,the positlon of the gear ring '39, for instance, in respect to the drum 19, a threaded member 72 is provided. This threaded member, as shownin Figure 8, is

provided with a stop 73 and a head 74. A screw member 75 is screwed into the gear wheel or ring 39 and is provided with an enlarged head 76, through which the shank 40 77 of the screw member 72 extends, whereby thefscrew member 72 lmay be freely row ytated, but cannot move longitudinally in respect to the' head76. A second threaded member 77 is screwed intothe flange 70,

'45 saidlthreadedmember 77 having a head 78 provided with a smooth guiding bore 79 in a threaded section 80 coacting with the threaded section of the screw member 72. By this construction and arrangement whenfever the head 74 is rotated, the flange 70 and the gear ring 39 will move in respect tov each other.- This will cause adjustment to align thevarious apertures 53 so as te coact with the apertures of the other drums. After all 5'5Pof the' drums have rbeen adjusted in like manner, the various wedges 71 are driven in or forced in until the parts are tight. AThese wedges are preferably .comparatively shert, as shown in Fig. 9, each wedge having a loosening.

means have been provi ed for 'aligning'the 83 adjacent each end. of the roller. This bracket accommodates a restricted part 84 of the shaft 85 ofvroller 37 (Fig. 10). A pin 86 is loosely mounted in the bracket 83 and is provided with a threaded aperture for accommodating the threaded'screw member 87. This screw member is rotatably mounted in a bracket 88 and carries a hand wheel 89 whereby the screw member may be of the machine, as shown in. Figure 2, andl as these are identical, no additional description will be necessary. The lever 92 is arranged only on one side as aduplication of this lever would not be necessary When,- ever desired, either of the hand wheels 89 may be rotated vfor properly aligning the roller 37, while the lever 92 is loose, for bodily shifting the roller in either direction. In regard to the aligning of the various part-s, it ','will be noted in Figure 3 that anti-friction rollers 95 and 96 are provided, said rollers being carried by screw bolt reciprocating `and guiding pins 97 Iand each pin surrounded with a spring 98 bearing against the fork 99 of the respective pins and against certain parts of the frame l, whereby a proper pressure will be maintained to hold the drum in a desired position. The springs 98 are comparatively stiff so as to firmly hold the drums in a given position, but in case of excessive strain, the drums yield, though the same will quickly return to their former position.

In operation, after the parts have been properlyaligned and the foundation cloth 32 arranged, as shown in Figure 1, the fabric 36 is threaded into the machine until it assumes substantially the position shown in Figure 1. The machine is then started and as it operates, the printing drum 18 prints dots of a certain color, while the printin rollers or drums 19 and 20 will print a dition-al dots either of the same color or different color and positioned in a desired relationship to the other dots. As the fabric leaves the machine, the various v,dots are, of course, still wetfand, consequently, the fabric laou is passed through a dryin apparatus of any A approved kind capableo dryin the paint 60 threaded extension 81 for-.receiving a nutf82, before 'the fabric is rolled or fo ded.
